Well, the boat floats. She is watertight. She sails!

Admittedly, she doesn't sail downwind (and won't until/unless I work out a way of fixing the malaligned steering gear), but she sails quite nicely upwind, and the cracked deck and gaping hull planks are both definitely a thing of the past.

It's quite weird spending an hour or so desperately attempting to 'tack' downwind, only for the boat inadvertently to gain so much to windward as to put her right back where she started; a complete inversion of the full-scale experience, as it were.

I think I've finally got the sail for my model yacht sorted out, after unpicking all the careful mending I had done (which made the leading edge too thick to fit up the slot in the mast) and substituting a piece of woven cotton tape as a repair for the damaged area.

The halyards are definitely ornamental only. You could never use those little bits of string to haul the mainsail up the mast; it takes both hands and all my coaxing to get it up.

(The hull did float, by the way!)

Six replaced shrouds later... I'm now wondering how to set up the rest of the rigging. Forestay and backstay required, I think. Complicated stuff under the boom. Unfortunately none of the model Dragons on the Web seem to be rigged anything like this one (I'm starting to wonder if it was ever intended as a sailing model at all, or just as a replica for display).

One thing my Web researches have demonstrated is that these models are pretty expensive to buy new...

The second coat of enamel has gone on now, after goodness knows how many layers of primer (seven? eight? ten?), and the hull is finally starting to look good. That is, smooth and shiny.

I thought I'd made another mess of it after the first coat of gloss enamel, which picked up every hint of a brushstroke in the primer beneath and had to be sanded back almost to nothingness -- but evidently this helped to 'seal' the surface in the manner of a first coat of varnish. At any rate, the second coat has been far more successful.

After almost two months a decent finish is almost within view... let's just hope the boat is actually watertight this time as well, after her spectacular quick-diving demonstration on her first flotation test..!

In a last-ditch attempt to avoid another eight-hour paint-stripping marathon (plus re-filling of all the holes, etc.), I resorted to Plan B on my model yacht's paintwork -- laying fresh strips of model aeroplane tissue over a fresh coat of wet primer where peeling away the bubbles of gloss paint had left gaping holes three layers of paint thick.

It seemes to have worked remarkably well.

This was the technique I was originally going to try, until persuaded by the man in the model shop that one couldn't possibly use tissue without doping it (which is fine on the convex curves of the hull, but proved fatal on the concave curves near the fin, since when the tissue contracts under the dope it inevitably pulls taut across the hollow and leaves a bubble). I suspect that it is, in fact, the technique that was intended by the old-time yacht restorers.

Everything depends on whether the tissue will pull tight again as the wet paint dries, or whether it will successfully have 'skinned over' the edges of the hole...

I made the mistake this morning of putting a coat of gloss paint on the hull of my latest model yacht restoration; after all, I'd already put on and sanded off two coats of undercoat, and as I knew on past precedent that I'd be putting on three-to-six layers of top coat before I got a smooth result, I thought I might as well launch straight into the gloss at this point, so that at least the hull would be waterproofed and I could do a flotation test, to see if I'd really sealed all the holes this time. And the tin says that it only requires onelayer of undercoat, so I must have done enough...

Mistake. First of all, there's more difference between ordinary exterior gloss and Humbrol than I'd realised (it's much thicker); secondly, it picks up and magnifies every single imperfection, like varnish, instead of smoothing over them the way the undercoat does. It certainly doesn't stick down bubbles, even if you slit them!

I really, really should have waited a couple of hours and covered over those exposed edges with yet another layer of undercoat first -- now I shall simply have to sand the whole lot off again. Sigh. And domestic gloss is probably a false economy, too, though I'll end up buying a lot of pots of Humbrol on a hull this size.
